Feb: 11, 1930. J. S 'OCH A wm'now FASTENER Filed May 31. 192 7 PatentedFeb. 11, 1930 T ()FFI JOHN SOGHA, OF SYRACUSE, NEWYORK WINDOW FASTENERApplication filed May 31,

This invention relates to new and useful improvements in fasteningdevices for w1ndows, and aims to provide a highlynovel, simple andinexpensive device comprising a certain structural element adapted forattachment to a pair of sliding sashesto permit the same to be securelyfastened in fully closed or any other predetermined open po sition.

In carrying out my invention there is provided a pair of units, one ofwhich is constructed for attachment to the front face of the uppersliding sash frame, the other unit being constructed for attachment tothe 1.3 upper bar of the lower sash frame, sa1d un1ts being associatedwhereby they may be 1nterlocked in various positions so that aspreviously stated, the sashes may be secured in predetermined open orfully closed position. so One of the most important Ob]6Cl3S of theinvention is to provide a fastener of this character that may be readilyassociated with the sash frame without materially alter1ng theconstruction thereof, and without obstructing 9:, the normal raising andlowering of the sashes.

In the drawing wherein like reference terconnected to maintain the lowersash in partially raised position.

Figure 2 is a fragmentary horizontal section through the upper sashdisclosing the upper end of the lower sash to top plan, and

4o said sashes being equipped with the elements of the invention.

Figure 3 is a side elevation of the amt rlgidly associated with theupper end of the lower sash. I

her that is and a r Figure 5 is a plan view of the movable fasteningmember of said unit.

Now having particular reference to the drawing, A designatesfragmentarily a window frame, while B and C indicate the upper and lowersliding sashes respectively. Rigidly secured to the inner face of theframe of the upper sliding sash B, and adjacent one side of the windowframe A is a vertically extending elongated metallic plate 5, the lowerendof'which is provided with an inwardly extending right angular lug 6for engagement within a cut out portion in the lower bar of the frame ofthe upper sash B. The outer face of this member 5 is formed with pairsof spaced fingers 6', the fingersof each pair converging toward eachotheras clearly indicated in Figure l and having slight spaced relationas disclosed. The invention further consistsof a narrow plate 7 having"openings 8-8 at its opposite ends, and which plate is adapted to bedisposed upon the top side of the frame of the sash, the openings 8-8being provided to permit the plate to be screwed or otherwise suitablysash frame, see Figure 2. This plate 7 is formed centrally with a raisedand circular portion 9 that is formed at the side adjacent the member 5of the upper sash with a notch 10. Furthermore, the center of the raisedcircular portion 9, is formed with an opening 11. r i

Disposed upon the top of the raised circular portion 9 of the said plate7 is a substan tially circular plate 12 also formed'centrally with anopening through which and through the opening 11 in the raised circularportion 9 of the plate 7 is arranged a pivot pin 13. The lower end ofthis pin is provided with an abutment 14, while surrounding the pincenter of the raised portion 8 of the sash attaching plate 7 is anexpansible coil spring for "causing an essential feature of said unit,

the frictional binding of the rotary plate 12 against said raisedcircular portion of the plate 7.

The edge of the movable plate 12 is formed throughout a portion of itsarea with a flange 16 that extends above and below said plate, asclearly indicated in Figures 1 and 4. One end of this flange terminatesin a tangential extension to provide a turning handle 19 for said plate.At the opposite end of the flange 16 said plate 12 is formed with anotch 20 for registry with the notch 10 of the raised circular portion 9of the attaching plate 7 so that when said notches are in registrationthe sashes may be raised and lowered without the plate 12 encounteringthe pairs of fingers 6 of the upper sash attached to member 5'. However,when the sashes are raised or lowered to a predetermined point, that isto a point whereby the turning plate 12 is directly between a pair ofthe fingers 6-6, a movement of the handle 19 in an inward direction willcausethefiange 16 of said plate to engage between the adjacent pair offingers 6' for obviously securing the sashes in such position.

In order to maintain the plate'12 against accidental turning movementwhen in secured or unlocked position, the said plate is provided on itsbottom side with a pair of spaced notches 2121 for receiving a tit 22 atthe top surface of the raised circular portion 9 of the sash attachingplate 7, the notches 21-21 obviously forcibly receive, the tit 22 byreason of the spring pivotal connection between the sash attached memberand said securing plate 12. t

In order that the upper and lower sashes may be moved without the unitsof the present fastener encountering each other, the backside of theframe of the lower sash C in registration with the notch 10 of theraised portion of'the anchoring plate 7 is slotted asat c and throughwhich slot the fingers of the upper sashpl'ate 5 are freely movable.

It will thus be seen that I have provided a highly novel, simple andinexpensive window fastening device that is well adapted for all thepurposesheretofore designated and even though I have herein, shown anddescribed the invention as consisting of certain detail structuralelements, it is nevertheless to be understood that minor changeszmay bemade therein without affecting. the spiritandrscope of the appendedclaim.

Having thus described the invention, what I claim and desire to secureby Letters'Patent is In a sliding window sash fastening means whereinone of the sashes is formed with a vertically disposed channel, anelongated plate secured in vertical position on the opposed-sash andadapted to ride in the; channel of the opposed sash when the latter ismoved, a rotary member mounted at the inner end of the said latter sashadjacent to the outer end of the said channel, the edge portion of thesaid member adapted to overlie said end of the channel, said memberbeing formed with a notch in its edge portion registerable with the openend of the channel, when the member is rotated to a certainpredetermined position, and pairs of spaced lugs on said plate forengagement by said member when the sashes are adjusted inwardly withrespect to each other.

In testimony whereof I affix my signature.

JOHN SOCHA.
